Dear Provost,

I am upset to hear about this new pandemic in Glenmarigg. This seems to be too much to bear on top of COVID, the cost of living crisis, and the war in Ukraine. It is just one tragedy after another.

I sincerely hope that your office is going to do something about horrible pandemic at once.

All the best,

Dear Provost,

This new pandemic in Glenmarigg has the potential to obliterate our businesses. I run a bookshop on the high street and almost went bankrupt due to COVID.

Things are bad enough already with the cost of living crisis, war in Ukraine, and Brexit, we can’t afford another pandemic.

I wish that your office is going to do something about horrible pandemic at once, keeping in mind the economic interests of businesses in our city and the fact that we cannot afford the draconian lockdowns you imposed during COVID.

All the best,
Siobhan (Around the Corner, proprietor)

Subject: Government Overstep

Dear Provost,

I hate the idea that you and your office are going to use this new pandemic as yet another excuse for government overreach into citizens’ lives. The mental health consequences of the last pandemic were underappreciated, but very real - people suffered due to the lockdowns and children’s development was affected by the wearing of face masks and the closing of schools.

Facemasks are just the tyranny of the minority over the majority, I hope that you will not permit them again on your watch.

All the best,
Luke (a concerned voter)

Dear Provost,

I have just learned that my my aunt has passed away due to the new pandemic in Glenmarigg. This is especially terrible coming hard on the heels of all of our losses due to COVID-19.

This is an unspeakable loss.

I am sure that you and your office are doing your best, but I hope that in the fullness of time, there will be a public inquiry into how this pandemic was handled and why so many families have lost loved ones. Especially coming so soon after the lessons that we learned during the COVID-19 pandemic, I would have thought that this tragedy could have been prevented.

Yours sincerely,
Luke
